Getting back to baldy baynes, there was Bald Eagle in Hillman's Air Fighters Comics. Also a couple of bald characters in British titles but I can't remember who or where.
Oh, of course, The Mekon from Dan Dare. What a great villain, right up there with the best comic book villains. Martian Manhunter, but that's another non-pd character. Going to check through some of the British comics sites, see if I can come up with others.
The British weekly, Battle and Valiant in 1977, had a war series called Darkies Mob, which featured Cap. Joe Darkie, a bald, British soldier. Series ran for quite a while, I think
Purely fyi, and not that I'm boasting, I have full head of hair, nicely cut by the young lady in The Barbers, Linlithgow.
